How do you write square root of 72 in algebra?

Mathematics
1 answer:
cupoosta [38]3 years ago
8 0
You would have the square root symbol (called a radical) over the number 72. But if you mean to simplify it, you can keep in mind that 9 x 3 = 72 and the square root of 9 is 3, so then your answer would be

3(radical)3

Hope that's not too confusing!

(2c^{-5})^{3} simplify ​
andrew-mc [135]

Answer:

Step-by-step explanation:

If this is

(2c^{-5})^3 then you distribute the 3 to both terms inside the parenthesis (the 2 and the c^-5).  2 cubed is 8.  The rule for the power to power is that you multiply the powers together to get -15.  So the final simplification is

8^{-15}

Our pool is twice as long as it is wide and is surrounded by a walkway of uniform width of 1 foot. The
Zigmanuir [339]

Step-by-step explanation:

x=width of pool

2x=length of pool

the dimensions of the rectangle forming the walkway and the pool are x+4 and 2x+4

the area of this rectangle minus the area of the pool is 196 square feet

(2x+4)(x+4)-(x)(2x)=196

2x^2+4x+8x+16-2x^2=196

combine similar terms

12x+16=196

12x=196-16

12x=180

x=180/12

x=15 feet is the width of the pool

check: 34*19-30*15=196

646-450=196

196=196

An excursion group of four is to be drawn from among 5 boys and 6 girls.
tresset_1 [31]

Answer:

Because you are recounting people several times. Say for example, let us number those people

{1,2,3,4} for the four girls and {1,2…7} for the boys.

One possible combination by your way is to fix one boy and girl each, say

{1,1} and then choose the remaining people. Let this combination be, for the sake of the example, {1,1,2,2,3}. This is a valid combination.

Now, when you fix another combination of a boy and a girl, say {1,2}, you could get the same combination as before because one the combinations while choosing the three remaining people would be {1,2,3}.

A correct way would be to choose  girls and then choose 5− boys for 1≤≤4

So we get ∑4=1(4)(75−)=441
