(-2ab^-5)(4a^-2b)^-2

enyata [817]

Answer:

-a^5/(8b^7)

Step-by-step explanation:

The applicable rules of exponents are ...

(a^b)(a^c) = a^(b+c)

(a^b)^c = a^(bc)

a^-b = 1/a^b

$(-2ab^{-5})(4a^{-2}b)^{-2}=(-2ab^{-5})(4^{-2}a^{-2(-2)}b^{-2})\\\\=\dfrac{-2}{16}a^{1+4}b^{-5-2}=\boxed{-\dfrac{a^5}{8b^7}}$

Rewrite the equation below so that it does not have fractions, Do not use decimals in your answer.

Paul [167]

Answer:

74/15

Step-by-step explanation:

$\frac{3}{4}$ x - 3 = $\frac{7}{10}$

to remove fractions multiply each side of equation by 40

3/4x(40) - 3 = 7/10(40)

120/4x - 120 = 280/10

simplify:

30x - 120 = 28

add 120 to each side to get:

30x = 148

x = 148/30 or 74/15 simplified
