What makes the statement true 7 negative 2 as a exponent equals?
7-2 = 1/72 = 1/49
What is x to negative 7th power?
When we have x to a negative exponent we can move the x to the denominator and make the exponent positive.So x-7 is the same as 1/x7 .In general if we have a-n then this is the same as 1/an .If you start with the negative in the denominator, then you can move it up to the numerator by changing the sign.
Why is a negative exponent minus a positive exponent a negative exponent?
when you're doing a problem like that use this trick. let's say you have 3 to the -7 power minus 3 to the 4 power. -7 - 4 can also be shown as -7 + -4. i switched the minus sign to a plus sign and because i did that, i had to switch the positive 4 to a negative 4. so i got 3 to the -7 power plus 3 to the -4 power.
What is 0.0000001 in exponent form?
1*10-7
What is the exponent answer for 7 to the 5th power times 1 7th to the 5 th power?
75 x (1/7)5 1/7 = 7-1 So, (1/7)5 = (7-1)5 = 7-5 Replacing this in the original expression gives, 75 x 7-5 = 7(5 -5) = 70 = 1 Alternatively, (1/7)5 = 15/75 = 1/75 we could then write, 75 x 1/75 = 1

Why is 7 to exponent 0 equal to 1?
why not !

How do you write 0.7 written as a fraction in simplest form without using a negative exponent?
7/10
What is the exponent answer for 7 to the 5th power times 1 7th to the 5 th power?
75 x (1/7)5 1/7 = 7-1 So, (1/7)5 = (7-1)5 = 7-5 Replacing this in the original expression gives, 75 x 7-5 = 7(5 -5) = 70 = 1 Alternatively, (1/7)5 = 15/75 = 1/75 we could then write, 75 x 1/75 = 1
How do you make an exponent of the exponent?
You multiply the exponents. For instance (23)3 = 29 : (54)1/2 = 52: (7-2)5 = 7-10
What is -5 to the power of 2?
7
What is a small number written in the upper right of the number?
It is called an exponent. Thus if you see 7 with a small number whose value is 5 in the upper right of 7, it means multiply 7 by itself 5 times, in other words it is a short hand notation for 7x7x7x7x7 which yields16807. The exponent can be negative. So 7 with a -5 in the upper right of 7 means the reciprocal of 7x7x7x7x7 or (1)/(7x7x7x7x7) which yields 0.000059499 The exponent can be a fraction. So 7 with a 1/2 in the upper right of 7 is asking the question "what number multiplied by itself yields 7" or what is the square root of 7. So in this case the value would be 2.64575 roughly. The exponent can be a negative fraction. So 7 with a -1/2 in the upper right of 7 is asking the question "what is the reciprocal of the square root of 7". The value would be 0.37796 roughly Hence the small number written in the upper right of a number is a short form widely used in science and mathematics to convey many precise meanings
The LCM for 14 and 20?
Factor both;Factors of 14 are 7 and 2Factors of 20 are 22 and 5.The highest exponent that appears for 2 is 2, the exponent for 5 is 1, and the highest exponent for 7 is 1.So we multiply.22 * 51 * 71 = 140
