Answer:
D
Step-by-step explanation:
a number expressed in standard form is
a × 
: 1 ≤ a < 10 and n is an integer
given
(7.5 × 
)(2 × 10³)
= 7.5 × 2 × 
= 15 × 
= 1.5 × 
×
= 1.5 × 
= 1.5 ×

Step-by-step explanation:
Answer:
x = 3.3
Step-by-step explanation:
A equation is given to us and we need to solve out for x. The given equation is ,
Take log on both sides with base as " 10" . We have ,
Simplify using the property of log , , we have ,
Simplify ,
Again simplify using the property of log ,
We know that log 5 = 0.69 and log 2 = 0.301 , on substituting this , we have ,
Simplify the RHS ,
Add 2 both sides ,
Hence the Value of x is 3.30 .
