Question

simplify pls give me in step by step answer ​

Answer 1

Answer:

1) 117649 2) 256

Step-by-step explanation:

1) (7^2)^3 = 7^(2*3) = 7^6 = 117649

2) {(2^3)^4 * 2^8} / 2^12

= 2^(3*4). *. 2^8. /2^12

= 2^12 * 2^8. / 2^12

= 2^(12+8). /. 2^12

=2^20 / 2^12

=2^(20-12)

= 2^8

=256

Answer 2

Step-by-step explanation:

$(a {}^{m}) {}^{n} = a {}^{mn}$

$(a {}^{m}) \times (a {}^{n} ) = a {}^{m + n}$

$(a {}^{m} ) \div (a {}^{n}) = a {}^{m - n}$

1) 7^6

2)

= (2^12 * 2^8)/2^12

= 2^(12 + 8) / 2^12

= 2^20 / 2^12

= 2^(20 - 12)

= 2^8
