Question

Write using exponents.
−3m⋅4⋅n⋅n
–7mn2
1mn2
12mn2
–12mn2

Answer 1

We have to simplify the expression $-3m.4.n.n$ using exponents.

By using the property of exponents, $a^m \times a^n = a^{m+n}$.

Consider the expression $-3m.4.n.n$

Since all the terms are getting multiplied, multiplying the constants together, and like variables together.

So, we get the product as

= $(-3 \times 4) (m)( n \times n)$

= $-12mn^2$

So, Option 4 is the correct answer.
