How do we know if we have to multiply or add exponents if the bases are the same?

You have to add the exponents. It's best if you just remember it. You can also consider what happens when you multiply something like:(2 x 2 x 2) x (2 x 2) As you can notice, the number of factors get added. That's like adding the exponents.

When multiplying fractions do you also multiply the denominator?

I dont know

Why don't we change the exponents during like terms?

Exponents are higher in priority in terms of the order of operations, and do not combine in the same way as you would simple add/subtract/multiply/divide. So, if you have: 26 + 24 This is a polynomial in base 2 with different powers. It would be this in binary: 1010000 ...which would not be the same as 210: 1000000000 In order to be able to change exponents, you have to be multiplying factors using the same base, as in: 26 * 24 = 210 ...because the exponents are also indicating how many times you are multiplying each base by itself, and multiplication is the same as the basal function of the exponent (repeated multiplication).

How do you do multiplication whole numbers?

Multiplication is nothing but repeated addition.We multiply whole numbers by referring to their multiplication tables and also by multiplying first the layer digit, then carrying off and then multiplying all the digits successively.

What is 0.000000001 of a kilometer?

0.000000001 is equal to one billionth, or 10-9. A kilometer is 103 meters. When multiplying exponents, add them together. In this case, we get 10-6, or one millionth of a meter - which can also be expressed as 0.000001.

What do you do with the exponents when you multiply two of the same variables?

To simplify, you write one copy of the base, then add the exponent. Example:x^5 times x^3 = x^8 In the case of positive integer exponents, this can easily be derived by writing each power as a repeated multiplication. However, this law is also valid for negative or fractional exponents.

What is 0.01 to the power of 10?

0.01 is also written as 1*10^(-2), (1*10^-2)^10=1*10^(-2*10), since raising exponents by to other powers is the same as multiplying the exponents together. The result is 1*10^(-20) or 0.00000000000000000001 (nineteen zeros after the decimal point).

Multiply by 100 percent?

If you multiply a number by 100%, you are simply multiplying by 1. You can multiply by 100% to change a decimal number or fraction to a percent. (0.25)(100%)=25%. You can also divide by 100% to change a percent to a decimal number. 65%/100%= 65/100 or 0.65.

How do you convert grade point average from 6.0 to 4.0?

When you multiply fractions by fractions what do you do to the numerators?

they are also multiplied. When multiplying fractions: (N1/D1) x (N2/D2). The new product is (N1 x N2) / (D1 x D2).

To find the mass of a rectangular object you multiply the objects length width and height?

A rectangular prism has a volume that can be found by multiplying the object's length width and height. To obtain the mass one must also know the density of the object and multiply that by the volume.

What is force newton meter?

Newton is a force. If you multiply Newtons times meters, you get an energy. The unit is also known by the name Joule, or watt-second. Multiplying Newtons times meters can also give you a torque (not related to energy).

How do you multiply and divide numbers with exponents?

If you have like terms then to multiply you add the exponents and to divide you subtract.So, x2 * x3 = x5 and y7 / y5 = y2Also, for example, 2x2 * x3 = 2x5 (we can do this as the terms are like; x's only)But if you do not have like terms then this does not apply.For example, x2 * y3 does not equal xy5.

Is multiplying an adjective?

It can be. It is a verb form (present participle) that can also be an adjective (multiplying rabbits) or a noun/gerund (multiplying creates a product).

How do you add exponents?

If the bases are the same then just do simple exponent addition just add hte exponents eg 2 to the power of 5 + 2 to the power of 3 = 2 to the power of 5+3 =2 to the power of 8 this can also be simplified to 1 to the power of 4

Why would you write a number in exponents instead of standard notation?

Writing a number in exponents usually becomes necessary in higher level mathematics. This is also necessary when the number of exponents becomes too great to reasonably fit.

Why when you multiply and negative number and a positive number it always equals a negative number?

This happens because a negative number is dominant over a positive one, so the number will multiply just as if you were multiplying even numbers, but at the end, just put a negative symbol. Also, if you multiply two negatives, they cancel themselves out, and the answer just becomes positive, but that only goes when multiplying an even amount of negative numbers together. For all of these, do the equation the same way, but at the end you may have to just add or take away a negative or positive symbol.
