Question

using the laws of exponents​

Answer 1

Answer:

$\frac{7^{4} * 6^{4}}{(42)^{2}}$ = 1764

Step-by-step explanation:

here, $\frac{7^{4} * 6^{4}}{(42)^{2}}$

      = $\frac{(7 * 6)^{4}}{(7 * 6)^{2}}$                [by taking power 4 common]

      = $(7 * 6)^{4 - 2}$          [by $\frac{a^{4}}{a^{2}}$ = $a^{4 - 2}$ ]

      = $42^{2}$

      = 1764
