Applying Properties of Exponents In Exercise, use the properties of exponents to simplify the expression.

Mathematics
1 answer:
NemiM [27]3 years ago
7 0

Answer: (a) e^3

(b) e^{10}

(c) \dfrac{1}{e^4}

(d) e^{4}

Step-by-step explanation:

Properties of exponents :

1) a^m\times a^n=a^{m+n}

2) \dfrac{a^m}{a^n}=a^{m-n}

3) (a^m)^n=a^{mn}

4) a^{-n}=\dfrac{1}{a^n}

Now , we simplify the given expression using the above properties.

a) (e^6)(e^{-3})

=e^{6+(-3)}   [By property (1)]

=e^{6-3}=e^3  [∵ (+)(-)=(-)]

b) (e^{-2})^{-5}

=e^{-2\times-5}  [By property (3)]

=e^{10}   [∵ (-)(-)=(+)]

c) (\dfrac{e^6}{e^2})^{-1}

=(e^{6-2})^{-1}    [By property (2)]

=(e^{4})^{-1}  

=\dfrac{1}{e^4}       [By property (4)]

d) (e^3)^{\frac{4}{3}}

=e^{3\times\frac{4}{3}}        [By property (3)]

=e^{4}

The volume of a cylinder is 980pi in ^3 The height of the cylinder is 20 in. What is the radius of the cylinder?
siniylev [52]

Answer:

The radius of the cylinder is 7 in

Step-by-step explanation:

To calculate the radius of a cylinder we have to use the following formula:

v = volume  = 980π in³

h = height = 20in

π = pi

r = radius

v = (π * r²) * h

we replace with the known values

980π in³  = (π * (r)²) * 20in

980π in³ / 20in = π * (r)²

49 in² = (r)²

√(49 in²) = r

7 in = r

The radius of the cylinder is 7 in

-2-5(4n-6)=-132 not really sure how to do this one ..
uranmaximum [27]

All you have to do is follow PEMDAS (if you don't know what that is, search it up).


-2-5(4n-6)=-132

Distribute the 5 to everything in the parentheses.

-2-20n+30= -132

Combine like terms.

-20n+28 = -132

Subtract 28 from both sides.

-20n = -160

Divide by -20 on both sides.

n = 8

Consider the circles shown. Circle A has a radius of 6 inches. Circle B has a radius 20% greater than
butalik [34]

Answer:

Answer should be D and E

Step-by-step explanation:

First, you need to figure out the radius of B.

As radius of A is 6 in, 20% of 6in would be 1.2in. So total radius of B = 6+1.2 = 7.2

Now you get the radius of B, calculate th area of B using the formula πr^2.

= π(7.2)^2 = 162.86 = area of B

Now, all answers except D and E is smaller than B. So, the answer would be D and E.
