Simplify the expression with using scientific notation (4 times 10 8)2
1 answer:
y = (4*10^8)^2 Both factors in the brackets are squared.
4^2 = 16
(10^8)^2 = 10^(2*8) = 10^16
y = 16 * 10^16
y = 1.6 * 10^1 * 10^16
y = 1.6 * 10^(1 + 16)
y = 1.6 * 10^(17) <<<<<< Answer I'd use the brackets unless instructed not to.

Step-by-step explanation:
7y+5+3y+5=70
10y+10=70
10y=60
y=6
7(6)+5= 42+5= 47
3(6)+5= 18 + 5 =23
47+23= 70
