Question

This is my question pls help!!!

Answer 1

$5 \times {e}^{3} \times {f}^{3} \times 4 \times \times {f}^{8} \times {e}^{6} \times {e}^{0} \\ = 5 \times 4 \times {e}^{3 + 6 + 0} \times {f}^{3 + 8} \\ = 20 {e}^{9} {f}^{11}$

Answer:

$20 {e}^{9} {f}^{11}$

Hope you could get an idea from here.

Doubt clarification - use comment section.

Answer 2

Answer:

$20 {e}^{9} {f}^{11}$

Show Work:

$5 \times {e}^{3} \times {f}^{3} \times 4 \times {f}^{8} \times {e}^{6} \times {e}^{0}$

$5 \times {e}^{3} \times {f}^{3} \times 4 \times {f}^{8} \times {e}^{6} \times 1$

$5 {e}^{3} {f}^{3} \times 4 {f}^{8} {e}^{6}$

$20 {e}^{9} {f}^{11}$
