Answer:
a = 2
b = 5
Step-by-step explanation:
Given :
(ar^b)^4 = 16r^20 ; a and b are positive integers :
Opening the bracket :
a^4r^4b = 16r^20
a^4 = 16 - - - - - (1)
r^4b = r^20 - - - (2)
a^4 = 16
Take the 4th root of both sides :
(a^4)^(1/4) = 16^1/4
a = 2
From (2)
r^4b = r^20
4b = 20
Divide both sides by 4
4b/4 = 20/4
b = 5
Hence ;
a = 2
b = 5
Answer:
looks like 3/4
Step-by-step explanation:
The two rational numbers between and is ,
<h3>How to find the rational numbers between -3/4 and -2/3?</h3>
In the form of p/q, which can be any integer and where q is not equal to 0, is expressed as rational numbers. As a result, rational numbers also contain decimals, whole numbers, integers, and fractions of integers (terminating decimals and recurring decimals).
given that -3/4 and -2/3
now take L.C.M between these two rational numbers is 12.
now multiply -3/4 with 3 both numerator and denominator
again multiply -9/12 with 4 both numerator and denominator
now multiply -2/3 with 4 both numerator and denominator
again multiply -8/12 with 4 both numerator and denominator
Hence the -36/48 and -32/48 are rational numbers between -3/4 and -2/3

Answer:
There are now six commonly accepted kingdoms. Each kingdom includes a set of organisms that share similar characteristics. The organisms in each Kingdom are considered biologically distinct from the others. The six Kingdoms are: Archaebacteria, Eubacteria, Fungi, Protista, Plants and Animals.
The given equations are;
2x-y=8......(i)
3x+y=17......(ii)
Adding equation (i) and (ii), we get
5x=25 ( as +y and -y is canceled out during addition)
Hence x=5
Now
Substituting the value of x in equation (i)
2x5-y=8
10-y=8
Hence y=2
