Question

help me guys plz...​

Answer 1

Hey mate ☺

$\huge{\mathfrak{\red{Answer}}}$

Given that,

${7}^{5} \times {7}^{ - 4} \times {7}^{ - 6}$

Formula-

${a}^{x} \times {a}^{y} \times {a}^{z} = {a}^{x + y + z}$

=

${7}^{5 + ( - 4) + ( - 6)}$

=

${7}^{ - 5}$

Note: If there is a - in power then the numerator goes down and denominator comes up.

There is no denominator so we take 1.

$\frac{1}{ {7}^{5} }$

=

$\frac{1}{16807}$

or

you can write 7 power -5.

Hope it helps...❣❣
