Question

49 × 〖(-7)〗^m = -343

Answer 1

Answer:

49×(-7)^m=-343

(7)^2×(-7)^m=(-7)^3

NOW THE BASE HAS THE SAME NO. (I.E.)7

SO WHEN BASES ARE EQUAL THE POWERS ALSO BECOME EQUAL

WE GET OUR EQUATION TO BE:

=>2+m=3 ....bcoz according to the law of

exponent when same bases are

multiplied the power gets added

=>m=3-2=1

Step-by-step explanation:

HOPE THIS WILL HELP YOU:)

Answer 2

Answer:

m=1

${ - 7}^{2} \times - 7 {}^{m} = - 7 {}^{ \\ \\ \\ bases \: nw \: same \: so \: m = 1$

so m=2
