Question

all the expressions that are equivalent to 4^-3

Answer 1

$\sf\small\underline\red{Answer:-}$

$\sf \: x^{-m}=\frac{1}{x^m} \\\sf so \\ \sf4^{-3} \implies\frac{1}{4^3} \sf \implies\frac{1}{32}$

so the possible expressions could be

$\large\sf\red{\frac{1}{4^3} \:and/or \: \frac{1}{32}}$

Answer 2

• 3(x + 2) and 3x + 6 are equivalent expressions because the value of both the expressions remains the same for any value of x. 3x + 6 = 3 × 4 + 6 = 18. and can also be written as 6(x2 + 2y + 1) = 6x2 + 12y + 6. In this lesson, we learn to identify equivalent expressions.

Answer 3

• 3(x + 2) and 3x + 6 are equivalent expressions because the value of both the expressions remains the same for any value of x. 3x + 6 = 3 × 4 + 6 = 18. and can also be written as 6(x2 + 2y + 1) = 6x2 + 12y + 6. In this lesson, we learn to identify equivalent expressions.
