a. 1^5 = 1 × 1 × 1 × 1 × 1 = 1
b. 2 × 2 × 2 × 2 × 2 = 2^5 = 32
c. 20^3 = 20 × 20 × 20 = 8.000
d. 7 × 7 × 7 × 7 = 7^4 = 2.401

The correct answer for that question is 280
Answer:
r = 0.0424 cm (3sf)
Step-by-step explanation:
it makes 150 rev/sec
1 revolution = 1 circumference = 2pi*r
so every second the spool goes through 2*pi*r*150 of distance
we know that the rate of pulling is 40cm/sec
so 2pi*r*150 = 40
r = 40/(2pi*150), which is 0.04244131816 cm.
check: Circumference is 2pi*r = 0.2666
now multiply by 150rev/sec = 40 cm/sec
Answer:
Option B.
Step-by-step explanation:
Integer: A non fractional complete number is known as integer. It can be either positive or negative or zero.
For examples : ...,-3,-2,-1,0,1,2,3,...
It is a clear that the difference between two consecutive integers is 1. It means we have to add 1 in the integer to get the next integer.
We need to express "next integer after the integer n" mathematically. So, we need to add 1 in n.
Required expression
Hence, the next integer after the integer n is n+1.
Therefore, the correct option is B.
