Answer:
1.) 8a⁴b³ + 6a²b³ab² - 2a²b³ab
2.) A. 44
3.) B. +83 degrees
4.) D. $0.15
5.) x⁴ - 256
6.) D. -122
7.) -6r²s⁴t³
Step-by-step explanation:
1.) To simplify, we simply multiply/distribute and then combine like terms.
2.) To simplify, we use Order of Operations BPEMDAS to solve.
3.) To find, we simply subtract 68 and -15 to get +83 as our answer.
4.) To find, we simply multiply 3 by 24 to get 72, then divide by $410.80 to get $0.15 as our answer.
5.) To expand/simplify, simply use Difference of Squares to get C. as our answer.
6.) To find the value, simply plug in 7 for <em>b</em> to get -122 as our answer.
7.) To find the result, remember that when you divide exponents, you subtract the powers.

Answer:
6.76
Step-by-step explanation:
applying pythogorem theorem
a^2+b^2=c^2
5^2+b^2=13^2
25+b^2=169
b^2=169/25
b^2=6.76^2
b=6.76
Answer:
7 × 10 + 3 × 1 + 3 × 0.1 + 8 × 0.01 + 5 × 0.001 > 73.293
Step-by-step explanation:
Given: Numbers are 7 × 10 + 3 × 1 + 3 × 0.1 + 8 × 0.01 + 5 × 0.001 and 73.293
To compare: the two given numbers
Solution:
7 × 10 + 3 × 1 + 3 × 0.1 + 8 × 0.01 + 5 × 0.001 is equal to ![73.385](https://tex.z-dn.net/?f=73.385)
Compare the numbers
and 73.293
Digits at the ones pace and tens place in both the numbers are same.
Observe the digit at the tenth place in both the numbers.
Digit at the tenth place in 73.385 is 3
Digit at the tenth place in 73.293 is 2
As
,
73.385 > 73.293
So,
7 × 10 + 3 × 1 + 3 × 0.1 + 8 × 0.01 + 5 × 0.001 > 73.293
