Answer:

Not sure exactly which equivalent expression you are looking for but my goal would be to write it without the negative exponent.

$\frac{1}{28^2}$

Step-by-step explanation:

They have the same exponent and it is multiplication.

There is a law of exponent that says $(a \cdot b)^x=a^x \cdot b^x$ .

So we have $4^{-2} \cdot 7^{-2}$ equals $(4 \cdot 7)^{-2}$ .

Let's simplify (4*7)^(-2).

Since 4*7=28, we can say $(4*7)^{-2}=(28)^{-2}$ .

Some people really hate that negative exponent. All that - in the exponent means is reciprocal. So $28^{-2}=\frac{1}{28^2}$ .

Since it varies directly, divide the number of shots by the number of goals:

48 shots / 4 goals = 12

This tells you they score a goal every 12 shots.

Multiply shots needed by number of goals:

12 x 3 = 36

They need 36 more shots to score 3 more goals.
