Question

simplify (-3)^10(-3)^-4

Answer 1

Answer:

729

Step-by-step explanation:

$-3^{10} (-3)^{-4}$

When we exponentiate a negative base by an even exponent, the base becomes positive.

The sign of the factor does not change.

In our example,

    the base is equal to 3 and

    the exponent is equal to 10.

$3^{10-4}$

$3^6$

$729$

☆Know about Laws of Radicals☆

Let a>0 be a real number, and let p and q be rational numbers, then we have:

• $(a^{p} \times a^{q}) = a^{(p+q)}$

• $(a^{p})^{q} = a^{pq}$

• $a^{p} /a^{q} = a^{(p-q)}$

• $a^{p}\times b^{p} = (ab)^{p}$
