Question

Find the value of (7³ x 49 ) ÷ 7² *

Answer 1

7³

Step-by-step explanation:

7³×49

49=>7²

=>7³×7²

7^5 (a^b×a^c=a^b+c)

7^5÷7²

=>7^5–2 (a^b÷a^c=a^b–c)

Answer 2

Step-by-step explanation:

$({7}^{3} \times 49) \div {7}^{2}$

$it \: can \: be \: written \: as$

$( {7}^{3} \times {7}^{2} ) \div {7}^{2}$

we know that a^m × a^n = a^m+n

$= ( {7}^{5} ) \div {7}^{2}$

a^m ÷ a^n = a^m-n

$= {7}^{5 - 2}$

$= {7}^{3}$

$343$
