Answer:
7^22
Step-by-step explanation
Given the expression
7^8 × 7^3 × 7^4 × 7^7
In indices
a^m × a^n = a^{m+n}
The powers are added since the base are the same
We ate going to add all the powers of the expression given since they have the same base which is 7
7^8 × 7^3 × 7^4 × 7^7
= 7^{8+3+4+7}
= 7^22
= 3.91×10^18
Answer:
It will remain -x/3
Only when you fix a value of x
then it can be simplified
The answer will remain negative until x is also negative
Answer:6/8
Step-by-step explanation: 4+2=6. Which is the numerator. 5+3=8. So the answer is 6/8.
