The term "power" is another term for a number's exponent. When there is a number raised to a power, you multiply that number by itself the amount of times equal to the power. For example: 43 The power, or exponent, would be the 3. This means you would multiply 4 by itself three times. 43 = 4*4*4 = 64 another example: 56 = 5*5*5*5*5*5 = 15625

multiply by 5 add 4

Multiply 6 and 4. Multiply 8 and 3.

3^5*4^5 = (3*4)^5 = 12^5

An exponent means "this many times." So, 4 cubed (to the power of 3; a 3 exponent.) is 4 NOT times 3, but 3 TIMES. So it is 4x4x4(=64). Or, 5 to the power of 5 is 5 times itself 5 times, so, 5x5x5x5x5(=3,125). 3 to the power of 9 is 3 times itself 9 times. Basically, the exponent tells how many times you multiply the number by itself. Does that help?

No, it is not. If you multiply 3 by 4, you get 12. However, you must multiply 5 by 5 to get 25, so it is not equivalent.

When you multiply 2 and 2 you get 4. 2x2=4

Multiply by is the usual form. Multiply 3 by 4 to get 12. If there are several numbers being multiplied then multiply .... together may be used... multiply 3, 4 and 5 together to get 60.

53 * 54 = 5(3+4) = 57 = 78125

There is a missing symbol between the 3 and 5 which I guess is a slash (ie you have the fraction 3/5); then: 4 Ã· 3/5 = 4 Ã— 5/3 = 20/3 = 6 2/3 = 6.666... â‰ˆ 6.667

4*3/5 = 12/5 = 2 2/5

To divide by a fraction, multiply by its reciprocal. In this instance, 4/5 / 1/3 = 4/5 x 3 = 12/5 = 2.4

the answer is 15/4 change the number 5 to 5/1. take 5/1 and 3/4 and multiply the top numbers. 5 x 3 = 15 then multiply the bottom numbers 1 x 4 = 4. set the two answers over each other to get 15/4

you turn the whole number into a fraction by putting it over one. example: 3/4 x 5 = 3/4 x 5/1 then you multiply like you do with all other fractions: 3/4 x 5/1 = 15/4 then you have to change the improper fraction into a mixed number 15/4= 3 3/4

To divide by a fraction, multiply by its reciprocal. In this instance, 4/5 / 1/2 = 4/5 x 2 = 1 3/5 or one and three fifths.To divide one fraction by another, multiply the first fraction by the reciprocal of the second. In this case, 4/5 divided by 1/2 = 4/5 x 2/1.

To divide a whole number by a fraction, multiply the inverted fraction by the whole number. Example: 5 divided by 3/4 = 5 * 4/3 = 20 / 3 = 6 2/3 Multiply by its reciprocal. 2/5 divided by 3/4 = 2/5 x 4/3 Invert the fraction and multiply. 4 / 1/2= ? 4 x 2/1 = 8

Find the LCD, which is 20, so multiply 3/4 by 5 and get 15/20, multiply 3/5 by 4 and get 12/20, so 15-12= 3, so 3/20

5 to the 7th power

The "invert and multiply" rules applies here: 1/3 divided by 4/5 = 1/3 * 5/4 = 5/12

Five and 3/4 as an improper fraction= 23/4 Five and 3/4 is a mixed number. Multiply 5*4+3=23 over the denominator, which is 4.

If you mean something like this: 54 then you multiply 5*5*5*5. The answer in this case would be 625. In any case with a number to a power, you multiply the number by itself however many times you have in the power. If it is just to the power of 2, you multiply it by itself twice. If it is to the power of 10, you multiply the number by itself 10 times. Most calculators (besides simple four-function calculators) have a button that allows you to input a number to a power and find the answer, which is much faster.
