Answer = 10=21
When you’re multiplying numbers with exponents with the same base (10 is the base) all you have to do is add the exponents
18 and 3 are the exponents we’re dealing with, so we add them and get 21. The base stays the same
10^18 x 10^3 = 10^21
Answer = 10=21
Answer:
B
Step-by-step explanation:
x² - 12x + 11 = 0 ( subtract 11 from both sides )
x² - 12x = - 11
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 6)x + 36 = - 11 + 36
(x - 6)² = 25 ( take square root of both sides )
x - 6 = ± 
= ± 5 ( add 6 to both sides )
x = 6 ± 5
Then
x = 6 - 5 = 1 ⇒ (1, 0 )
x = 6 + 5 = 11 ⇒ (11, 0 )

Answer:
3.5x10³
Step-by-step explanation:
7x10^5=700000
2x10^2=200
Divide both by 100
7000÷2=3500
divide by 1000 as standard form is less than 10
1000 is 10 cubed
3500÷1000 is 3.5
∴3.5x10^3 is answer
Step-by-step explanation:
x = 21/4 fraction form and alternative form is 5 1/4
