Answer:
21/3-(-101/6)
Final result :
143
——— = 23.83333
6
Step by step solution :
Step 1 :
101
Simplify ———
6
Equation at the end of step 1 :
21 101
—— - (0 - ———)
3 6
Step 2 :
7
Simplify —
1
Equation at the end of step 2 :
-101
7 - ————
6
Step 3 :
Rewriting the whole as an Equivalent Fraction :
3.1 Subtracting a fraction from a whole
Rewrite the whole as a fraction using 6 as the denominator :
7 7 • 6
7 = — = —————
1 6
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
Adding fractions that have a common denominator :
3.2 Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
7 • 6 - (-101) 143
—————————————— = ———
6
6 6
Final result :
143
——— = 23.83333

Answer:
1. no
yes
yes
2. d¹/³ b is the final answer
Step-by-step explanation:
1. a surd is just an irrational number, so a radical or a never-ending decimal
2.
simplify like we did to the others by distributing the exponent through the parentheses, then combining like terms, and finally combining fractions.
b⁻⁵(cd⁻¹)³ → b⁻⁵c³d⁻³
d(bc²)⁻¹ → d b⁻¹c⁻²
<u> d⁻⁵b⁻⁸ </u> → <u>d⁻²b⁻³ </u> → d⁻²b⁻³c⁻³
b⁻⁵c³d⁻³ c³
<u />
<u>d b⁻¹c⁻² </u> → d b⁻⁴c⁻³
b³c
divide
<u> d⁻²b⁻³c⁻³</u> → d⁻³b
d b⁻⁴c⁻³
positive indices are just positive exponents; it wants you to make the exponents positive. to do that you find the reciprocal, so you turn the negative exponent into a fraction under the number one and get rid of the negative.
d¹/³b
