Question

Simplify the following expression.

4a^-2b

Answer 1

\(\Huge 4a^{-2}b\) ?

Answer 2

yes

Answer 3

negative exponent always has its base reciprocated

Answer 4

for example: \(\Large x^{-n}\)is same as \(\large\dfrac{1}{x^n}\)

Answer 5

So after what I have explained so far, can you simplify \(\Large 4a^{-2}b\) ?

Answer 6

1/4a

Answer 7

exponent -2 doesn't apply to 4 nor b, just a

\(4a^{-2}b = 4(a^{-2})b\)

Answer 8

do you know what to do to variable with negative exponent to make exponent positive?
