Answer 1

Answer:

7

Step-by-step explanation:

{(7²)³ ×7⁸} ÷ 7¹³

= 7⁶ × 7¹³ ÷ 7 ¹³

= 7¹⁴ ÷ 7¹³

= 7

Answer 2

Answer:

7 power 1 or we can say 7 itself  

Step-by-step explanation:

answer will be 1 as  7 is same , so taking 7 as common  then in first term it is written (7 power 2) *3  so in exponents where their is this type of condition the powers will multiply.

so, it will be 7 power 2*3 which will be 7 power 6.

then it is given that 7 power 6 is multiplied by 8  so in exponents where we have to multiply it will add.  so our first term was 7 to the power 6 + 8 (here we have added the powers as multiplication sign is given)

then our answer is 7 to the power 14

then their is division sign so in exponents we subtract when division is their  so our answer was (7 to the power 14 - 13) here i have subtracted the powers because 7 we have taken as common  so our answer will be 7 to the power 1
