10. what is the answer in scientific notation?
(3.3 x 107) + (7.7 x 108)
a 8.03 x 10^9
b 8.03 x 10^8
c 11 x 10^8
d 11 x 10^9

answer: 1, 3 and 5 are correct

step-by-step explanation:

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!

k

step-by-step explanation:

domit

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.
