Answer :

Step-by-step explanation :
To find the product of

First we expand the bracket ,
it implies that, we use the expression outside the bracket to multiply individual expressions inside the bracket.
Hence


we now apply the law of indices

meaning, when you are multiplying two expressions with the same bases , repeat one of the bases and add the exponents.
Then, simplify to obtain
To decrease an amount by 7% what single multiplier would you use. You want 7% less than 100%, so the answer is (100%-7%)=93% =0.93. Hope I helped!
Answer:
1) 5
2) 5
Step-by-step explanation:
Data provided in the question:
(3²⁷)(5¹⁰)(z) = (5⁸)(9¹⁴)(
)
Now,
on simplifying the above equation
⇒ (3²⁷)(5¹⁰)(z) = (5⁸)((3²)¹⁴)(
)
or
⇒ (3²⁷)(5¹⁰)(z) = (5⁸)(3²⁸)(
)
or
⇒ 
or
⇒
or
⇒
we can say
x = 5, y = 2 and, z = 3
Now,
(1) y is prime
since, 2 is a prime number,
we can have
x = 5
2) x is prime
since 5 is also a prime number
therefore,
x = 5
Fraction of the total was seen=(number of people were seen ) /(Total number of people)
Data:
number of people were seen=440
Total number of people=people saw +people didn´t see=440+360=800
Fraction of the toatal was seen=440/800=11/20
Answer: 11/20.
