$frac{4k times 6k {}^{2} }{3 ^{2} k {}^{2} }$
2.tentukan nilai m dari persamaan berikut!

a.
$frac{4 {}^{7} times 4 {}^{3} }{4 {}^{m} } = 4 {}^{2}$

b.
$frac{2 {}^{m} times2 }{2 {}^{2} } = 2 {}^{4}$
tolong bantuannya

Penjelasan:

$1)frac{4k times 6k {}^{2} }{3 ^{2} k {}^{2} } \ = frac{ {2}^{2} k times 2.3 {k}^{2} }{ {3}^{2} {k}^{2} } \ = frac{ {2}^{3} {k}}{3}$

$frac{4 {}^{7} times 4 {}^{3} }{4 {}^{m} } = 4 {}^{2} \ frac{ {4}^{10} }{ {4}^{m} } = {4}^{2} \ {4}^{10 - m} = {4}^{2} \ m = 8\ \ b. frac{2 {}^{m} times2 }{2 {}^{2} } = 2 {}^{4} \ frac{ {2}^{m} }{2} = {2}^{4} \ {2}^{m - 1} = {2}^{4} \ m = 5$
