Answer:
Step-by-step explanation:
The given expression:
Step 1: Change radical to fractional exponent.
Formula for fractional exponent:
The power to which the base is raised becomes the numerator and the root becomes the denominator.
Step 2: Apply law of exponent for a product
Multiply powers with same base.
Take LCM for the fractions in the power.
Hence the simplified form of .
Answer: 511
Step-by-step explanation:
53.
For this problem simply plug in the numbers: 1 through 9 for n
the n=1 on the bottom represents the start and the 9 at the top represents the end
and the 2^n-1 represents the rule
solving for a1: plugging in one for n
a1=2^1-1
a1=1
a2=2^2-1
a2=2
a3=2^3-1
a3=4
a4=2^4-1
a4=8
a5=2^5-1
a5=16
a6=2^6-1
a6=32
a7=2^7-1
a7=64
a8=2^8-1
a8=128
a9=2^9-1
a9=256
after finding all these values add them all together and you should get your answer
1+2+4+8+16+32+64+128+256
=511
To find f(3), plug x = 3 in f(x),
∴ f(3) = 3(3)+1 = 9+1 = 10
Therefore, the ordered pair is (3,10)
For second one,
plug x = 10 in f⁻¹(x),
f⁻¹(10) = 10-1/3 = 9/3 = 3
Therefore, the ordered pair is (10,3)
If you would to solve 60% of 85 is what number, you can calculate this using the following steps:
60% of 85 is x
60% * 85 = x
x = 60% * 85 = 60/100 * 85 = 51
Result: 60% of 85 is 51.
We can say that the other number is even or it is 0.
