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:
40/140 ≈ 0,2857 corresponds 28,57%.
Answer:
-1
Step-by-step explanation:
To find the slope, the formula is y2-y1 divided by x2-x1
y2 = -4
y1 = -2
x2 = -1
x1 = -3
-4+2 = -2
-1+3 = 2
-2/2 = -1
4x+24=84 4x=60 x=15 length =27 width = 15
234 then 230
11 then 10
230/10=23
Estimate 23
