Which expression are equivalent to 1/5 × 1/5×1/5×1/5​

Mathematics
1 answer:
lys-0071 [83]3 years ago
4 0

Answer:

<h2>A and D</h2>

Step-by-step explanation:

1/5 is the same as 5^(-1),

so (1/5)^4=5^(-4)

as we know,

when you multiply the bases, you add the exponents

when you divide the bases, you subtract the exponents

when you simplify a term with and exponent with another exponent, you multiply them

so,

a)

(5^(-2))^2=5^(-2*2)=5^(-4)

b)

(5^(-4))^0=5^(-4*0)=5^0

c)

5^(1)/5^(4)=5^(1-4)=5^(-3)

d)

5^(2)*5^(-6)=5^(2-6)=5^(-4)

The two answers are A and D

If Jaime is riding at 14 miles per hour and Cori is riding at 0.40 km per minute, how far will each of them bike in two hours? 1
user100 [1]

Answer:

just take speed =distance ÷time

dustance is speedxtime

14x1.61=22.54÷60 to change to min =0.37km per minute

0.40x0.37= 0.148 km

perhaps I may get wrong

Just general definitons:

a TRInomial has 3 terms (tri means three)
a BInomial has 2 terms (bi means two)
a MONOmial has 1 term (mono means one)

the degree is the highest exponent found in the algebraic expression

so they should be pretty easy to solve with that information, but just in case:

1. trinomial, degree of 4
2. binomial, degree of 3
3. monomial, degree of 2

for the final question, all you have to do is plug in 2 for x, so

(2)^2 - 2(2) + 1

4 - 4 + 1

so the answer is 1

Identify which of the following is not equivalent to 2 3/4.
mezya [45]

The figure that is not equivalent to 2¾ is 2¼ × 2½. That is option B.

<h3>Simplification of equivalent fractions</h3>

Simplification is a process that is used to make a fraction appear in its simplest forms.

The fraction given is = 2¾

The simplification of the fraction= 2^3/4 = 2

But simplification of 2¼ × 2½ is equal to;

2¼= 0.5

2½= 1

Therefore 2¾ is not equivalent to 2¼ × 2½ when simplified.
