Answer 1

Answer:

2⁶×7⁹/2³×7⁴

2³×7⁵

this is your answer and if you want to do it more you can split them and can do it.

Answer 2

Step-by-step explanation:

$\mathfrak \color{yellow}{your \: question} :$

$\frac{ {2}^{4} \times 2 \times {7}^{3} \times {7}^{6} }{ {2}^{3} \times {7}^{4} }$

$\mathfrak \color{green}{your \: answer} :$

$= \frac{ {2}^{4 + 1} \times {7}^{3 + 6} }{ {2}^{3} \times {7}^{4} }$

[ use property of indices:

(a)^m * (a)^n = (a)^m+n. ]

$= \frac{ {2}^{5} \times {7}^{9} }{ {2}^{3} \times {7}^{4} }$

[ now divide the values by using this property of indice:

a^m ÷ a^n = (a)^m-n ]

$= {2}^{5 - 3} \times {7}^{9 - 4}$

$= {2}^{2} \times {7}^{5}$

[ find out the squares and fives of the numbers ]

$= 4 \times 16807$

[ multiply it ]

$= 67228$
