I think the answer is 300 because 4 is less tvhan 5 and when you round numbers, if the number is less than you leave it or if it is 5 or more you add one more.
Answer:
-3.5+27
Step-by-step explanation:
-2.7+x=-3.5
x=-3.5-(-2.5)
x=-3.5+2.5
x=2.0
The exponent of the power is 11 in scientific notation.
<h3>Given </h3>
The numbers are;
The product of (9. 1 × 10^9)(7. 5 × 10^2)
<h3>What is scientific notation?</h3>
Scientific notation is a method of expressing numbers in terms of a decimal number between 1 and 10, but not 10 itself multiplied by a power of 10.
To find the product of the given numbers follows all the steps given below.
The product of number is;

Hence, the exponent of the power is 11 in scientific notation.

Answer:
Yes, it's correct. Is that what you were asking for, or is there a part of the question that is missing?
Step-by-step explanation:
Answer:
See below.
Step-by-step explanation:
I'll work it out myself, then we should be able to see the mistake:-
6 ∛ (64x^5y^9)
= 6 * 4 * x^(5/3) * y^3
= 24 x^(3/3) * x^(2/3) y^3
= 24 x y^3 ∛(x^2)
You've got confused withe the cube root (∛) on the first line. You've interpreted it as ' 3 times the square root' so you were on the wrong road from the beginning.
Note that y^9 has cube root y^(9/ 3) = y^3 and x^5 has cube root of x^(5/3). The square root of x^9 is x^(9/2).
