Answer:
D) ½
Step-by-step explanation:
∛(x√x) = xᵇ
Cube both sides.
x√x = x³ᵇ
Square both sides.
x² x = x⁶ᵇ
x³ = x⁶ᵇ
Equate the exponents.
3 = 6b
b = ½
The width of the triangle is supposed to be 164 cm
7.48×10⁻² the process is shown in the following picture
Answer:4/10 =2/5
Step-by-step explanation:
you subtract the numerator but the denominator stays the same. I then found a number that could be divided into both numbers and got 2/5.
Given expression is x² - 121
This is called Difference of Squared terms, we have a formula that is given as :-
a² - b² = (a - b) · (a + b)
Now using the above formula in the given expression, we get :-
x² - 121
x² - (11)²
here a = x and b = 11
x² - (11)² = (x - 11) · (x + 11)
but it says that student gave the answer as (x - 11) · (x - 11).
So, student's answer should be (x - 11) · (x + 11) instead of product of two (x - 11) terms.
